From Your Instructor

Welcome to AP Cybersecurity

This course runs across two trimesters with a gap in between — which means how we sequence things matters more than in most classes. Trimester 1 builds the foundations you need to survive that break. Trimester 3 applies them, goes deeper, and gets you ready for the AP exam.

The PLTW labs, cyber cases, and credential are the backbone of this course for everyone. The AP content is layered on top of that — extra depth, exam prep, and the option to sit for the AP exam in May. You can complete the course on the PLTW track alone, or opt into the full AP track. Either way you get the same labs and the same cyber cases; the AP track just adds the exam-focused material and the exam itself.

Understanding cybersecurity isn't optional knowledge anymore, and not just on a global scale. The same techniques you'll study here — phishing, weak passwords, unpatched systems, social engineering — are what take down hospitals, water treatment plants, and school districts, and they're exactly how individual accounts and identities get compromised every single day, including yours. What you learn here protects more than a grade.

Take the labs seriously, don't skip the steps that build up to each cyber case, and use whichever path — PLTW alone or the full AP track — actually fits you.

A Note About AI

  • Format and layout lesson content consistently
My advice about using AI

You're in a cybersecurity course. This semester you'll learn exactly how AI-generated content is weaponized — deepfakes, AI-written phishing, synthetic documentation. If you use AI to fake your own understanding, you're practicing the attacker's playbook on yourself.

Bottom line: Use AI to understand — not to replace understanding. If you submit work you can't explain, that's plagiarism, and I will know.
